Wood burning stove - radiator/back boiler - advice please

[chocccie]

I am thinking of changing the wood burning stove we installed for another one with a back boiler. 

I'm looking to run four radiators off it and would appreciate any tips or advice you could give me (just radiators, no hot water supply needed). 

I have searched on the internet and all I can find is references to central heating / hot water installations with another additional heating source.

Do I need any sort of expansion tank or can I just connect the stove to the radiators with a pump?

We discussed just this in this thread

The system we ran in the UK which I mention, did indeed operate on a pump and rads alone - no expansion tank as far as I remember.

A wood fired heating system will need an open vent which would normally feed back into the header tank at the highest point in the system. One or more radiators will need to be on the gravity circuit to provide some heat dissapation in the event of a power cut or pump failure. The remaining radiators can be on the pumped circuit and can, therefore, be at the same level or lower than the boiler. There are a number of other design considerations in order to create a safe and efficient heating system.

I'm hoping to start the installation in the next week or two.  I'm going to run 4 radiators off a wood burning stove - 2 upstairs, 2 downstairs.

Any tips or advice will be very gratfully received.

Thanks  [:)]
